摘要：
In this paper, we have mathematically analyzed lumped element type negative group delay circuit (NGDC) and derived general design equation. The applicability of the proposed design equation is validated with mathematical and circuit simulation as well as with experimental results for international mobile telecommunication 2000 (IMT-2000) downlink band. As a design example, single branch NGDC with-0.8ns of group delay (GD) for narrow bandwidth of the specific frequency is simulated and fabricated. Finally, it-network NGDC is proposed and validated to obtain wideband GD response of-1.7±0.06 nsec for 60 MHz.
